ABSTRACT:
A dot-code recording method includes a step of generating a plurality of one-block dot patterns, each of which comprises a plurality of dots. The plurality of one-block dot patterns are then arranged to represent multimedia information, and a specific range of the plurality of one-block dot patterns are distributed according to specific rules to thereby arrange the one-block dot patterns within the specific range in non-time sequence. The non-time sequence distributed one-block dot patterns are then recorded on a recording medium.
